Overview of this book

NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems. This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended. By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.

SCPI commands sets

As more and more test instruments using different buses and protocols entered engineering and test labs, a need for standard and universal sets of commands, as well as syntax and data formats to program and automate these devices, became a necessity. In 1990, IEEE 488.2 completed the standard that started with IEEE 488.1. This standard covers classes of instruments as well of product-specific commands. Although this standard was originally designed to accommodate a GPIB bus using ASCII text strings, it can also be used in USB, Serial and RS232 and Ethernet other lesser known architectures.

As an example, if we look down in the lower levels of NI drivers and examples to automate a Tektronix TD 2022, we will find standard SCPI commands:
